Description

[Detailed description of the invention] (Field of industrial application) This invention relates to a metering stopper used for dispensing a fixed amount of liquid such as medicines, cosmetics, detergents, etc. in squeeze bottles and gargles. It is.

(Prior Art) Conventionally, this type of fixed-dose dispensing device for a fixed-dose medium stopper has a dispensing cylinder having a dispensing hole at its upper end protruding in the vertical direction at the center of the bottom plate of the main body of the medium stopper. Moreover, the lower end of this pouring cylinder was formed to fit a suction pipe. By pressing the body of the squeeze bottle, the liquid inside the squeeze bottle is discharged from the spout hole into the inner stopper body through the suction pipe and the spout cylinder.

Further, as a metered dispensing device, the lower end of the dispensing cylinder is supported on the outside of the upper end of the supporting cylinder by means of screwing means so that the height can be adjusted freely (for example,
No. 27289), and those in which the inside of the lower end of the spouting cylinder is supported on the outside of the upper end of the support cylinder so that the height can be adjusted freely by a sliding means that contacts the opposing peripheral surfaces (for example, 14982 Publication), or one in which the dispensing cylinder is supported inside the support cylinder so that its height can be adjusted freely by sliding means using engaging protrusions protruding inward at the upper and lower ends of these (for example, in actual use). Publication No. 59-3848), etc. were proposed.

(Problem to be solved by the invention) However, with the former, it is not possible to adjust the height of the dispensing cylinder, so it is difficult to adjust the required amount of liquid to be dispensed from the squeeze bottle depending on the type of liquid and individual differences. It was not possible to set it arbitrarily. Further, not only is it troublesome and impossible to adjust the height of the spouting cylinder reliably, but also the stability of the supporting state of the spouting cylinder is poor.

On the other hand, in the latter, the lower end of the dispensing cylinder is simply supported vertically from above by screwing means to the upper end of the support cylinder of the quantitative dispensing device, so the pressing force when dispensing the liquid is There was a drawback that the spouting cylinder was pulled out from above the supporting cylinder when the height of the spouting cylinder was adjusted upward. In addition, as a sliding means when adjusting the height of the spouting cylinder, it can be done by contacting the opposing peripheral surfaces of the support cylinder and the spouting cylinder, or by adjusting the height of the support cylinder and the spouting cylinder. This is done by the engagement protrusion on the end, which not only makes it troublesome and impossible to adjust the height of the dispensing cylinder reliably, but also prevents the dispensing cylinder from being placed inside the support cylinder of the quantitative dispensing device. Since it was supported by only one engagement protrusion at the upper end, the stability of the supporting state of the pouring cylinder was also poor.

Therefore, the present invention was devised to solve the above-mentioned problems, and it is possible to arbitrarily set the required amount of liquid to be dispensed from the squeeze bottle according to the type of liquid and individual differences. Moreover, not only can the height of the dispensing cylinder be easily and reliably adjusted, but also the stability of the support state of the dispensing cylinder is good. To provide a metering stopper that can reliably prevent a dispensing cylinder from being pulled out from above a supporting cylinder when adjusting the height of the dispensing cylinder upward.

(Means for Solving the Problems) In order to achieve the above-mentioned object, the present invention has a bottom plate of a bottomed cylindrical inner stopper body that fits tightly into the mouth of the squeeze bottle. A quantitative dispensing device is provided for dispensing a fixed amount of liquid, and this dispensing device has upper and lower parts, which have a large diameter part on the upper end side and a small diameter part on the lower end side, in the center of the bottom plate of the inner stopper body. A support cylinder that is long in the direction is provided so that the large diameter side projects upward and the small diameter side projects downward. Provide an upper protrusion receiving part that matches the inner diameter of the part,
The inner side of the support cylinder has a spout hole at the upper end of the cylinder whose outer diameter matches the inner diameter of the small diameter part on the lower end side of the support cylinder and the inner diameter of the upper protrusion receiving part. A dispensing cylinder which is elongated in the vertical direction and has a sliding protrusion on the outer circumferential surface of the substantially central part thereof in the vertical direction, the outer diameter of which matches the inner diameter of the large diameter part on the upper end side of the support cylinder; The upper protrusion receiving part and the upper end of the small diameter part on the lower end side of the support cylinder are slid between each other so that the small diameter part on the lower end side of the support cylinder and the upper protrusion receiving part are pressed into contact with each other. The height of the hole is adjustable, and a suction pipe is connected below the support cylinder of this quantitative dispensing device, the lower end of which reaches the bottom of the squeeze bottle.

(Function) By the above-mentioned technical means, the spouting cylinder is mounted on the support cylinder so that the sliding projection slides between the upper projection receiving part and the upper end of the small diameter part on the lower end side of the support cylinder. The height of the spout cylinder can be easily adjusted by moving in the vertical direction while being pressed against the inner peripheral surface of the lower end side small diameter part and the upper protrusion receiving part, and
The vertically long dispensing cylinder can be supported at two points: the small diameter part on the lower end side of the vertically long supporting cylinder and the upper protrusion receiving part. When the sliding projection moves to the uppermost position when adjusting the height of the cylinder, the sliding projection is locked to the upper projection receiving part of the support cylinder.
